The Trajan Arch is one of the most important symbols of Benevento and was erected in 114 A.D. in honour of Emperor Trajan on the occasion of the inauguration of the Via Appia, the road connecting Brindisi to Rome. The work, decorated with splendid reliefs, is one of the most important triumphal arches during the Roman era.
The arch reaches 15.6 metres in height and 8.6 metres in width; each front is composed of four half-columns supporting the entablature.
Near the Arch, the Church of St. Hilary is located; inside the latter, it is possible to visit the ‘Museum of the Arch’, in which there is a multimedia installation that evokes the life and deeds of the Emperor Trajan depicted on the reliefs of the Arch.
